Not every 21st is about drinking

In the US, 21 is the legal drinking age, and many 21st messages lean on it. That works for some people, but plenty of 21-year-olds don't drink or would rather celebrate another way. In the UK, Ireland, Australia and New Zealand, 21 has long been marked as a coming of age, and some families still give a key as a symbol of being free to come and go.

A good 21st message works whatever the plans are:

  1. 1.Happy 21st, with their name.
  2. 2.Something you've seen in them over the last few years.
  3. 3.A wish for their twenties.

Speeches at a 21st

At a 21st party there's often a speech, usually from a parent or a best friend. Keep it short: a childhood story, one quality you admire, a wish for their twenties, then a toast. Leave out any story you wouldn't tell in front of their grandparents.

What to avoid

  • Drinking jokes for someone who doesn't drink or is in recovery.
  • Pressure about degrees, jobs or relationships.
  • Comparisons with siblings, or with how you were at 21.

If you missed it

Send a belated message with a plan attached: a dinner, a call, or a card with something small inside. A 21st is worth celebrating a week late.

Frequently asked questions

What do you write in a 21st birthday card?
Name the milestone, mention something you've seen in them over the last few years, and wish them well for their twenties. A short, proud message is better than a long joke.
What should parents write for a 21st?
Tell them what you admire about the adult they've become and that home is always there for them. Add a favorite memory if you like.
What's a good 21st message for a friend's son or daughter?
Something short and generous: congratulate them on the milestone, mention one thing you've noticed about them over the years, and wish them a great start to their twenties.
Why do people give a key for a 21st birthday?
It's a tradition from the UK, Ireland, Australia and New Zealand, where 21 was long seen as the coming of age. The key stood for the freedom to come and go. Today it's usually a decorative keepsake.
